ALFRED s. DIOKINSON, OF WASHINGTON; DISTRICT Or COLUMBIA. Lette/rs Patent No. 85,433, dated December 29,4 1868A.

IMPROVED CURTAIN-FIXTURE.

To all 'whom -it ma/y concern:

Be it known that. I, ALFRED S. Dicmsos, of Washington, in the District of Columbia, have invented a new and useful Improvement in Window- Gurtain Fixtures; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making part of this specification, in which- Figure lis a perspective View of a window, with the' curtain attached. Figure 2 is a vertical section of the same.V

Figure 3 is a front elevation.

The same letters indicate the same parts in the several figures.

My'improvements' relate to that class ot'.\vindow curtains which are attached to a roller fastened upon oscillating arms, so that the curtain may be either raised or lowered, byorolling .Or unrolling it in the ordi-V nary manner, or it may be lowered so-as to admit light and air through the upper .part of the window, by causing the oscillating arms to swing forward from the window-easing. v

The natiue and extent of my invention will appear from the following specification and claims.-

In the annexed drawings- A represents the casing of a window, and

B, an ordinary curtain-roller, upon which the curtain C may be rolled, by means of the cord B, in the ordinary manner.

An objection tothis form of curtain has been that, while excluding the light,l it also excludes the air.

My improvement is intended to avoid this objection,-

by a cheap and convenient construction, as follows:

The roller is made to turn in bearings attached to theends of a wooden or metallic strip, D.

This strip isattached to two rods E E. These rods are made in a'single piece, and have a suitable head cast upon their upper ends, to receive the strip D.

Another mode of constructing and attaching these rods, which I propose to use, is to make the rods of The width of thev curtain and. length of the strips Dl should be greater than the width of the opening of the window-frame, so that, when the strip is drawn back by the' cord F, which is fastened at the centre, and

carried through two eyes or pulleys F' in the casing, arn nged as shown, the arms will project slightly forward, as shown'in iig. 2. The advantage of this ar rangement is that, whenever the cord F is loosened,

the strip D and top of the curtain will fall forward by gravity merely, so that it will not be necessary to draw it down.

The band or cord Gr may be stretched across the windoweframe, from side to side, below the pivots of the arms, so that the curtain,` while the-top is swung forward, shall be held close to the window at the lowe end.

I do not claim an oscillating arm as a support for the roller, for I am aware of the patent of R. M. Fenton, dated June 25, 1867, of which I Own-an undivided half interest. j

My improvements are distinguished from Fentous curtain-fixture in the following particulars:

First, by .attaching the roller-strip to rods pivoted to the inner face of the window-frames, I am enabled to cast the arms in a single piece, instead of in two pieces joined by a hinge;

Second, by thus attaching it, the rods are made to project forward at the top, so as to' swing 4downward and forward by gravity merely, so that it is not necessary to draw the curtain forward by the hand, as in Fentons arrangement; j

Third, by attaching the vcord at the middle of the strip, the latter is balanced, and therefore not liable to sag at one side, as is the case with Fentons, which is suspended at one end of the strip;

' Fourth, the curtain, when raised, entirely conceals the arms; and

Fifth, it is 'materially cheaper.

What I claim as my invention, and desire to secure .by Letters Patent, is-

1. The .combination of the curtain-roller, and the bearings therefor, attached to a strip, D, and said strip,

and the rods E, attached thereto, and pivoted to the inner and opposite faces of the window-casing, said' parts being arranged, in relation to one another, to operate substantially in the manner set forth.

2. In combination with the oscillating arms, roller, and strip, the cord F, centrally attached to the strip, and passing through l pulleys or eyes F', substantially as and for the purpose set forth. A

In testimony whereof, I have signed my name to this specification, in the presenceof two subscribing witnesses. j
